EDGE-TRIMMING TOOL.

SPECIFICATION forming part of Letters Patent No. 228,456, dated June 8, 1880.

Application led March 24, 1880.

To all whom it may concern:

Be it known that we, GEORGE E. GOODING and EUGENE H. TAYLOR, both of Lynn, in the county of Essex and State of Massachusetts, have invented an Improved Edge-Trimming Tool, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to improvements in a tool for edge-trimming the soles and edges of boots and shoes, and has for its object the production of a tool having interchangeable parts, which, if broken or worny out, may be readily renewed. A

Our edge-trimming tool is of that class in which the system of guides and gagesis clasped upon the blade of a shoe-knife of ordinary or suitable construction.

In this our invention we employ a block having attached to it a clip by which to adjustably secure the block and its attached parts upon the knife-blade. This block has adjustably connected with it a vertically, horizontally, and laterally adjustable edge-gage. The guard to run in the rand-crease, or between the rand and upper, is made as a separate piece from the block. Separating the edge-trimming tool in this way into independent parts secures economy in the cost of tools.

Figure l represents one of our edge-trimming tools shown as applied to a shoe-knife blade, the blade and parts of the tool being shown in working position with relation to the edge of a shoe-sole; Fig. 2, a right-hand-side elevation of the toolshown in Fig. 1, the blade of the knife being omitted. Fig. 3 shows the guard separated from the block; Fig. 4, an end view looking upward from Fig. l, the blade being omitted; Fig. 5, a top view of Fig. 2; Figs. 6 and 7, inner-side and outer-side views of a modification to be referred to, and Fig. 8 an end view of the guard used in Figs. 6 and 7.

The block a has attached to it, by the screw I), the clamping-plate c, preferably made of spring metal, so as to clamp the blade d of any usual shoe-knife between itself and the block in the space e. But one screw is herein needed for this purpose, as the front end of the clamp is fitted into a recess in the block behind a stud or clamp-holder, 2, (see Fig. 2,) forming part of the block a.

(No model.)

The guard f, which is to run in between the rand g and. slice-upper 7L, is of usual shape; but, instead of forming part of the block a, its shankf is provided with a screw-hole, 3, and a shoulder, 4, Athe former to receive a screw, 5, and the latter to enter a proper groove made for its reception in the said block a, thus permitting the guard to be renewed. One block a will ontlast a number of guards.

The block a is suitably grooved (see Fig. 4) to receive the shank z' of the gaging devices. As herein shown, one edge of the said shank i is conned by the separable anged plate k and the two screws l. The shank i, when in adjusted position, is held against longitudinal movement by the screw 6. The shank has at its lower end a dovetailed or other equivalent shaped guide-head, m, which enters a dovetailed groove in a slide, a, which, at its opposite side, has a second dovetailed or equivalent shaped groove at right angles to the length of thefblock (see Fig. 2) to.receive the horizontally-adjustable plate 0, that at its outer end has a stud, 8, upon which is placed the edgegage p, herein shown as a roller.

The plate o has an elongated slot, 10, to receive the set-screw 12.

Adjusting the plate on the slide n controls the thickness of the chip taken from the soleedge. Adjusting the block longitudinally on the part m enables the'roller-gage to bear upon the material to be trimmed in the proper positionwith relation to the cutting-edge of the knife-blade to insure a smooth cut, this'adjustment providing for change of position as the knife, in grinding, is Worn away.

The adjustmentprovided for by set-screw 6 enables the gage to be run along the edge of the sole as near the welt as possible, but preferably not upon the welt, for the sole-edge cut out by a die is smoother and more regular than the edge of the welt.

Instead of supporting the roller-gage as hereinbefore described, we may extend the guard f upward, as in Figs. 6 and 8, slot it at 13 to receive a screw, 14, by which to adjustably secure to the said guard the plate r, which, in function and purpose, is the equivalent of the plate o, hereinbefore described. This plate r has a stud, upon which is held the roller edge- IOO We claim- 1. In an edge-trimming tool, the block provided with the projection 2, combined with the clamp c and the screw Z), substantially as described.

2. rlhe guard to run in the rand-crease7 and provided with a screw-hole and notched part 4, combined with the block a, grooved to receive the part 4:, and the screw 5, by which to attach the shank j" to the block, as described.

3. The block [a and its attached guard, coinbined with the edge-gage l?, made adjustable toward and from the outer edge of the said guard to regulate the thickness of the chip or piece to be trimmed from the sole-edge, substantially as described.

4. The block a and gua-rd, combined with the edge gage, supported substantially as described, and made adjustable in the direction of the length of the gagef to adapt the gage to the edge of the knife-blade whatever may be its width.

5. rlhe grooved block aand clamp and guard, combined with the shank fi, adjustable on the block, and the grooved slide n, plate, and edgegage, to operate substantially as described.

(i. In an edge-trimming tool, the block and clasp to hold a knife-blade, combined with the guard j', to more in the rand-crease, and the wheel-like edge-gage p, substantially as described.

In testimony whereof" we have signed our names to this specification in the presence of two subscribing witnesses.
